SYS$FAO coding example in BLISS-32

(I posted about this on the VSI forums, but am posting here in case
there are any old VMS hackers hanging out only here.)

Does anyone have an code example of calling SYS$FAO in a BLISS program?

I'm trying to teach myself the language from old manuals and want a way
to print text and numeric data from programs to my terminal. I've found
the TUTIO package, but would like to know a method that also works in
batch mode. SYS$FAO looks like a useful way to format data into
character strings for output with LIB$PUT_OUTPUT, but I've so far only
succeeded in printing blank lines, and can only find coding examples in
MACRO or FORTRAN.
